I remember sitting in a class at Columbia and wondering why students were asking so many pointless questions, designed to show how much they knew rather than establish anything useful.

In my university (Oxford, Modern History) you feared looking stupid by asking questions at lectures, and instead asked your friends afterwards and read up yourself.

Different cultures, none are perfect, I guess.

I imagine Feynman's lectures would have made me feel "too stupid to ask". Probably says more about me than him :)
